What is bno transformer oil used for in power transformers?

BNO transformer oil is used for insulation and cooling in power transformers. It serves as an electrical insulating medium, preventing arcing and dielectric breakdown, while also dissipating heat generated during operation. BNO transformer oil is formulated to have high thermal stability and low viscosity, ensuring efficient performance and longevity of the transformer. Its properties help maintain optimal operating conditions and enhance the reliability of power transformers.
